本文建立了双层玻璃幕墙(DSF)的简化热工模型,并采用热阻网络图,对温度矩阵及DSF热工性能进行了编程求解。基于求解结果,分析了幕墙结构尺寸及玻璃组合对幕墙换热的影响。结果表明:夏季工况下玻璃的光学性能对DSF热工性能的影响最大;在DSF玻璃光学性能确定的条件下,窄通道DSF热通道宽度对室内得热量的影响显著,宽通道DSF遮阳百叶位置对室内得热量的影响较大。
In this paper, a simplified thermal model of double-glazed curtain wall (DSF) was established. The thermal matrix and thermal performance of DSF were programmed and solved by using thermal resistance network. Based on the results, the influence of the size of the curtain wall structure and the glass combination on the heat transfer of the curtain wall was analyzed. The results show that the optical properties of DSF have the greatest influence on the thermal properties of DSF in summer. Under the condition of DSF glass optical properties, the width of DSF hot aisle has a significant effect on indoor heat gain. Indoor heat has a greater impact.
